DOI: 10.1007/s10884-016-9541-7
Abstract: In this paper, we study the localized rotating spots created by the spatially inhomogeneous feedback. We adopt the wave front interaction model proposed by Zykov and Showalter in 2005. The existence of rotating spots in… read more here.

DOI: 10.1016/j.ijresmar.2020.11.005
Abstract: Abstract We propose a new spatial modeling approach to calibrate the potential impact of spatial dependency and heterogeneity on the underlying drivers of customer service and/or satisfaction measurement. The newly proposed procedure identifies regionally varying… read more here.
